Description

Technical Field

[0001] The invention belongs to the technical field of hanging equipment and relates to a stable downhill device for a vehicle and hanging equipment. Background Art

[0002] In the current hanging equipment, according to the requirements of the site layout, a downward turning and downhill structure is often used, and the vehicle does not move smoothly during the unpowered downward movement. This is because when the vehicle running on the track is pushed downhill, it will inevitably accelerate, causing the momentum and kinetic energy of the vehicle to suddenly increase, causing the vehicle to move unstably and fall or hit the push rod in front, causing the vehicle to derail, the push rod to break, and other accidents caused by excessive shaking.

[0003] The existing solution is to add a deceleration block before going downhill to reduce the initial speed of the vehicle going downhill; or to reduce the inclination angle of the ramp, such as a hanging conveyor line disclosed in application number 202021584268.1.

[0004] In the structural solution of the prior art, the vehicle still accelerates when the vehicle is on a slope, and the speed is too fast, which makes it difficult to solve the above-mentioned defects existing in the hanging device. Summary of the invention

[0005] In view of the above problems existing in the prior art, the present invention provides a device for stabilizing downhill movement of a vehicle. The technical problem to be solved by the present invention is: how to make the vehicle move more smoothly when going downhill.

[0006] The purpose of the present invention can be achieved by the following technical solutions:

[0007] A vehicle stabilizing descent device, characterized in that the vehicle stabilizing descent device comprises a base, a movable push block is installed on the base, a rotating push rod is hinged on the push block, the outer end of the rotating push rod can extend from one side of the base, a driving member 1 for driving the push block to move and a sensing element for triggering the action of the driving member 1 are also installed on the base, and a driving member 2 for making the outer end of the rotating push rod extend to one side of the base is also installed on the base.

[0008] In the above-mentioned vehicle stable descent device, the second driving member includes a reset member connected between the base and the rotating push rod, and the sensing element is a photoelectric switch for detecting whether the inner end of the rotating push rod is close, and the photoelectric switch is installed on the base.

[0009] Its working principle is: the stable downhill device of the carrier is installed on the hanging equipment, the hanging equipment includes a main beam and a track, the track has a horizontal section and a lower curve, and a plurality of push rods are slidably connected to the main beam, and each push rod moves synchronously. Before going downhill, the clothes hanger is hung on the horizontal track, that is, the horizontal section of the track, and the push rod pushes the clothes hanger to move forward at a uniform speed. When the hanger rod touches the outer end of the rotating push rod, the vertical rod of the hanger (that is, the hanger rod) pushes the rotating push rod to rotate forward. When the hanger rod pushes the rotating push rod to the limit position, the hanger rod bypasses the rotating push rod. At this time, the inner end of the rotating push rod enters the sensing area of ​​the photoelectric switch, and the photoelectric switch detects the rotating push rod. After the rod is extended, a signal is sent to instruct the driving member to perform a telescopic action. At the same time, the rotating push rod returns to its original position under the action of the reset member until the inner end of the rotating push rod abuts against the side wall of the push block. The driving member acts quickly after receiving the signal. The driving member pushes the push block to move. The outer end of the rotating push rod arranged on the push block pushes the hanger forward at a speed faster than the push rod. The driving member retracts quickly after extending to the limit. After the hanger moves to a certain position, it touches another push rod in front that has just entered the lower bend. Due to a certain slope, the hanger cannot return, but continues to contact with the push rod in front, and moves at a uniform speed with the push rod in front, and steadily goes downhill.

[0010] The vehicle stabilizing downhill device allows the vehicle (such as a clothes hanger) to be pushed in advance on the horizontal track before entering the curve to the push rod in front of the vehicle that has just entered the downhill slope, so that the vehicle can smoothly run over the steep slope next to the push rod in front. The vehicle has a uniform speed when going downhill, which reduces shaking and collision, ensures stable operation of the vehicle, and reduces the risk of accidents. In the above-mentioned vehicle stabilizing downhill device, the driving member 1 includes a cylinder 1, the cylinder 1 has a piston rod, and the push block is installed on the piston rod.

[0011] In the above-mentioned vehicle stable descent device, a pneumatic throttle valve is provided on the cylinder 1.

[0012] The extension and retraction speed of the cylinder can be adjusted by adjusting the pneumatic throttle valve, and the adaptability is good.

[0013] In the above-mentioned vehicle stabilizing descent device, the first driving member is a cylinder or a linear motor.

[0014] In the above-mentioned vehicle stabilizing descent device, a guide pin is arranged on the base, the push block comprises a bottom plate, a slide groove is provided on the bottom plate, and the guide pin is located in the slide groove and can slide relative to the slide groove.

[0015] In this structure, the guide pin and the slide groove form a guide structure. When the push block moves, the slide groove on the bottom plate moves relative to the guide pin. The guide pin plays a good guiding role and can improve the stability of the push block when it moves.

[0016] In the above-mentioned vehicle stabilizing downhill device, the push block comprises a bottom plate, the edge of the bottom plate has a convex edge, and the inner end of the rotating push rod can abut against the convex edge.

[0017] After the rotary push rod is reset, the inner end of the rotary push rod abuts against the convex edge of the bottom plate, and the convex edge supports the rotary push rod to prevent the rotary push rod from continuing to rotate.

[0018] In the above-mentioned vehicle stabilizing downhill device, the middle portion of the rotating push rod is hinged on the push block, and the inner end portion of the rotating push rod has a protrusion extending toward the photoelectric switch.

[0019] When the hanger rod pushes the rotary push rod to the limit position, the hanger rod bypasses the rotary push rod. At this time, the protrusion on the inner end of the rotary push rod enters the sensing area of ​​the photoelectric switch, making it easier for the photoelectric switch to detect the rotary push rod, thereby improving the convenience of operation.

[0020] In the above-mentioned vehicle stabilizing downhill device, the reset member is a spring in a compressed state, one end of the spring abuts against the middle of the rotating push rod, and the other end of the spring abuts against the push block.

[0021] In the above-mentioned vehicle stabilizing downhill device, the reset member is a rubber block, one end of the rubber block abuts against the middle of the rotating push rod, and the other end of the rubber block abuts against the push block.

[0022] In the above-mentioned vehicle stabilizing descent device, the base has an inner cavity, the inner ends of the driving member 1, the push block and the rotating push rod are located in the inner cavity, and an upper cover capable of covering the inner cavity is detachably fixed to the top of the inner cavity.

[0023] The inner ends of the driving member 1, the push block and the rotating push rod are located in the inner cavity of the base, and the upper cover covers the inner cavity. This structure hides a part of the driving member 1, the push block and the rotating push rod, and plays a certain protective role for these components.

[0024] The upper cover can be detachably fixed to the top of the inner cavity by means of buckles, and is easy to disassemble and assemble.

[0025] In the above-mentioned vehicle stabilizing descent device, both sides of the base are provided with bosses for embedding into the hanging bracket.

[0026] Multiple brackets are fixed between the main beam and the track of the hanging equipment. The base is located between adjacent brackets. During installation, the bosses on both sides of the base are respectively embedded in the corresponding brackets to complete the coordination and fixation of the base and the bracket, which greatly improves the convenience of installation.

[0027] In the above-mentioned vehicle stabilizing descent device, the second driving member includes a second cylinder installed on the base, the piston rod of the second cylinder is connected to the inner end of the rotating push rod, and the sensing element is a card reader for detecting whether there is a vehicle, and the card reader is installed on one side of the track of the hanging device.

[0028] The present invention also provides a hanging device, which includes any one of the above-mentioned vehicle stabilizing descent devices.

[0029] Compared with the prior art, the advantages of the present invention are as follows:

[0030] 1. This vehicle descent stabilization device allows the vehicle (such as a clothes hanger) to be pushed in advance on the horizontal track before entering the curve to the push rod in front of the vehicle that has just entered the slope of the descending curve, so that the vehicle can smoothly run over the steep slope close to the push rod in front. The vehicle has a uniform speed when going downhill, reducing shaking and collision, ensuring stable operation of the vehicle and reducing the risk of accidents.

[0031] 2. The guide pins and slide grooves of the vehicle's stable downhill device form a guide structure. When the push block moves, the slide groove on the bottom plate moves relative to the guide pins. The guide pins play a good guiding role and can improve the stability of the push block when it moves. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] The following are specific embodiments of the present invention, and the technical solutions of the present invention are further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0039] Embodiment 1

[0040] like Figure 1-2 As shown, the vehicle stabilizing descent device comprises a base 1, on which a movable push block 2 is mounted, on which a rotating push rod 3 is hinged, and the outer end of the rotating push rod 3 can extend from one side of the base 1, and the base 1 is also provided with a driving member 5 for driving the push block 2 to move and a sensing element for triggering the action of the driving member 5, and the base 1 is also provided with a driving member 2 for making the outer end of the rotating push rod 3 extend to one side of the base 1.

[0041] like Figure 2 As shown, in this embodiment, the second driving member includes a reset member 4 connected between the base 1 and the rotating push rod 3, and the sensing element is a photoelectric switch 6 for detecting whether the inner end of the rotating push rod 3 is close, and the photoelectric switch 6 is installed on the base 1.

[0042] like Figure 3 As shown, the stable downhill device of the carrier is installed on the hanging device, and the hanging device includes a main beam 19 and a track 20. The track 20 has a horizontal section and a lower bend 23. A plurality of push rods 21 are slidably connected to the main beam 19, and each push rod 21 moves synchronously. Before going downhill, the hanger 22 is suspended on the horizontal track 20, that is, on the horizontal section of the track 20. The push rod 21 pushes the hanger 22 to move forward at a uniform speed. When the hanger rod touches the outer end of the rotating push rod 3, the vertical rod of the hanger 22 (that is, the hanger rod) pushes the rotating push rod 3 to rotate forward. When the hanger rod pushes the rotating push rod 3 to the limit position, the hanger rod bypasses the rotating push rod 3. At this time, the inner end of the rotating push rod 3 enters the sensing area of ​​the photoelectric switch 6. The photoelectric switch 6 detects that the rotating push rod 3 After the push rod 3 is extended, a signal is sent to instruct the driving member 5 to perform the extension and retraction action. At the same time, the rotating push rod 3 returns to its original position under the action of the reset member 4, until the inner end of the rotating push rod 3 abuts against the side wall of the push block 2. The driving member 5 quickly acts after receiving the signal, and the driving member 5 pushes the push block 2 to move. The outer end of the rotating push rod 3 arranged on the push block 2 pushes the hanger 22 forward at a speed faster than the push rod 21. The driving member 5 is extended to the limit and then quickly retracted. After the hanger 22 moves to a certain position, it touches another push rod 21 in front that has just entered the lower bend 23. Due to a certain slope, the hanger 22 cannot return, but continues to contact with the front push rod 21, and moves at a uniform speed with the front push rod 21, and steadily goes downhill.

[0043] like Figure 2 As shown, in this embodiment, the driving member 5 includes a cylinder 7, the cylinder 7 has a piston rod 8, and the push block 2 is installed on the piston rod 8.

[0044] like Figure 2 As shown, in this embodiment, a pneumatic throttle valve 9 is provided on the cylinder 7. The telescopic speed of the cylinder 7 can be adjusted by adjusting the pneumatic throttle valve 9, and the adaptability is good.

[0045] As another embodiment, the driving member 5 may also be a cylinder or a linear motor.

[0046] like Figure 2 As shown, in this embodiment, a guide pin 10 is provided on the base 1, and the push block 2 includes a bottom plate 11, and a slide groove 12 is provided on the bottom plate 11. The guide pin 10 is located in the slide groove 12 and can slide relative to the slide groove 12.

[0047] In this structure, the guide pin 10 and the slide groove 12 form a guide structure. When the push block 2 moves, the slide groove 12 on the bottom plate 11 moves relative to the guide pin 10. The guide pin 10 plays a good guiding role and can improve the stability of the push block 2 when moving.

[0048] like Figure 2 As shown, in this embodiment, a convex edge 13 is provided on the edge of the bottom plate 11 , and the inner end of the rotary push rod 3 can abut against the convex edge 13 .

[0049] After the rotary push rod 3 is reset, the inner end of the rotary push rod 3 abuts against the convex edge 13 of the bottom plate 11 , and the convex edge 13 supports the rotary push rod 3 to prevent the rotary push rod 3 from continuing to rotate.

[0050] like Figure 2 As shown, in this embodiment, the middle portion of the rotary push rod 3 is hinged on the push block 2 , and the inner end portion of the rotary push rod 3 has a protrusion 14 extending toward the photoelectric switch 6 .

[0051] When the hanger rod pushes the rotating push rod 3 to the limit position, the hanger rod bypasses the rotating push rod 3. At this time, the protrusion 14 on the inner end of the rotating push rod 3 enters the sensing area of ​​the photoelectric switch 6, making it easier for the photoelectric switch 6 to detect the rotating push rod 3, thereby improving the convenience of operation.

[0052] like Figure 2 As shown, in this embodiment, the reset member 4 is a spring 15 in a compressed state, one end of the spring 15 abuts against the middle of the rotating push rod 3, and the other end of the spring 15 abuts against the push block 2.

[0053] As another embodiment, the reset member 4 is a rubber block, one end of the rubber block abuts against the middle of the rotating push rod 3 , and the other end of the rubber block abuts against the push block 2 .

[0054] like Figure 2As shown, in this embodiment, the base 1 has an inner cavity 16, and the inner ends of the driving member 5, the push block 2 and the rotating push rod 3 are located in the inner cavity 16. The top of the inner cavity 16 is detachably fixed with an upper cover 17 that can cover the inner cavity 16.

[0055] The inner ends of the driving member 5, the push block 2 and the rotating push rod 3 are located in the inner cavity 16 of the base 1, and the upper cover 17 covers the inner cavity 16. This structure hides a part of the driving member 5, the push block 2 and the rotating push rod 3, and plays a certain protective role for these components.

[0056] The upper cover 17 can be detachably fixed to the top of the inner cavity 16 by means of buckles, and is easy to assemble and disassemble.

[0057] like Figure 1 and 3 As shown, in this embodiment, both sides of the base 1 have bosses 18 for embedding into the hanger 24 .

[0058] A plurality of hangers 24 are fixed between the main beam 19 and the track 20 of the hanging equipment, and the base 1 is located between adjacent hangers 24. During installation, the bosses 18 on both sides of the base 1 are respectively embedded in the corresponding hangers 24 to complete the coordination and fixation of the base 1 and the hangers 24, thereby greatly improving the convenience of installation.

[0059] Embodiment 2

[0060] The structure and principle of this embodiment are basically the same as those of the first embodiment, except that Figure 4 and 5 As shown, the second driving member includes a second cylinder 25 installed on the base 1, the piston rod of the second cylinder 25 is connected to the inner end of the rotating push rod 3, and the sensing element is a card reader 26 for detecting whether there is a carrier, and the card reader 26 is installed on one side of the track 20 of the hanging device.

[0061] In this embodiment, the push rod 21 pushes the carrier (such as a clothes hanger 22) forward at a constant speed. When the push rod 21 pushes the carrier to the front of the card reader 26 next to the carrier's stable downhill device, the card reader 26 senses and reads the chip information on the carrier. The system will automatically judge based on the running speed of the push rod 21. After a delay of T1, the vehicle's stable downhill device will be activated. Based on the time consumed for each complete action of the vehicle's stable downhill device (the time is taken as T2), the card reader 26 is allowed to continue processing the next vehicle information after a delay of T3.

[0062] The driving action of the vehicle's stable downhill device is two-stage:

[0063] The first section is a pushing action, which is designed to take T4. When the vehicle stable downhill device receives the action command, the cylinder 25 moves from the default fully extended state to the fully retracted state and maintains it. The cylinder 25 drives the rotary push rod 3 to rotate to the pushing state, and the outer end of the rotary push rod 3 extends from one side of the base 1. The action is designed to take t1 (t1 is slightly greater than the time required for the cylinder 25 to retract). After t1, the cylinder 1 7 moves from the default fully retracted state to the fully extended state. The cylinder 1 7 drives the push block 2 to move forward, and the moving speed is greater than the moving speed of the push rod 21. The action is designed to take t2 (t2 is slightly greater than the time required for the cylinder 1 7 to extend), where t1+t2=T4.

[0064] The second section is the homing action, and the design time is T5. After the first section is completed, the cylinder 25 moves from the fully retracted state to the fully extended state, and the cylinder 25 drives the rotating push rod 3 to rotate to the default initial state, waiting for the next instruction, and the design time is t3 (t3 is slightly greater than the time required for the cylinder 25 to extend); after t3, the cylinder 1 7 retracts, and the cylinder 1 7 pulls the push block 2 back to the initial state, and the time is t4 (t4 is slightly greater than the time required for the large cylinder to retract), where t3+t4=T5.

[0065] The present invention also provides a hanging device, which includes any one of the above-mentioned vehicle stabilizing descent devices.

[0066] The specific embodiments described herein are merely examples of the spirit of the present invention.
